Question

A pulley system has three pulleys. A load of 60 N is overcome by applying an effort of 12 N. Calculate its mechanical advantage.

Answer 1

Given Data:

Load (L) = 60 N

Effort (E) = 12 N

Calculation:

Mechanical Advantage (M. A.) = `"Load"/"Effort"`

= `60/12`

= 5

The mechanical advantage of the system is 5 (it has no unit).
